摘要

The invention relates to the field of borehole drilling, in particular to a device for centering a drill string, a warning spontaneous curvature wells. The object of the utility model is to reduce the wear of the centering elements and the torque loss. This problem is solved in that the centralizer Hydraulics-mechanical variable geometry centering elements comprising the sleeve, which is connected to the hollow rod, dies mounted movably tapered housing sub hydraulic channels, a cylinder, a piston-pusher, the rubber ring, cuff pressure ring and a steel shoe according to the proposed solution between the hollow rod and cone clutch mounted bearings allowing rotation of the centralizer relative to the centering element in - dies.
